Figure '7 is a view in front elevation, showing the meansforfrictionally mounting the month hand for adjustment on the calendar.

Figure 8 is a detail view in perspective of the main shaft, showing aportion of the day disk in which'said main shaft is fixed.

Figure 9 is a detail view in perspective of the thrust sleeve.

Referring now to the drawings in detail, it will be seen, thattheembodiment of the invention which has been illustrated comprises afaceplate 1 of suitable material, preferably. heavy'cardboard,havingsuspension means thereon, as at 2, for mounting the calendar on a'wall'or other support. Arranged in a circular series on the front ofthe face plate 1 are date numerals 3 'from 1 'to 31, inclusive. Thefrontof'the face plate 1 is also provided with the names of the monthsof the year equi-distantly spaced in a circular series within the dates3, as at 4.

Fixed in the face plate l'centrally with respect to the days and'months3 and 4 is a tubular bearing 5 having a head 6 integral with one endthereof'and engaged against the rear of said face plate 1. Prongs '7 onthe periphery of the head 6 penetrate the faceplate 1 and are clinched,as,

best seen in Figure 6 ofthe drawings, in a manner 'to secure the bearing5 in position. A washer I the'b'earing 5 in front of the face 8 ismounted o platellb a Mounted'for rotary adjustment on the forwardportion of the bearing 5 is a month'hand 9, said month hand beingimmediately adjacent the washer 8-. The month hand 9 is frictionallysecured in adjusted position on the bearing 5 through'the medium ofresilient clamping jaws l0-which are secured, at one'end, on anintermediateportionof said month hand 9, and which have-their other endportions engaged in an an;- nular groovell which is provided therefor;the forward end'portion of the bearing 5.. It will thus be seen that theclamping jaws 10 provide means forretaining the month hand 9 in positionon thebearingfi inadditionto'frictionally securing said month handinadjusted position. Themonth hand 9 termina'tes adjacent the months 4onythe face r n The reference numeral ,12- designates the day disk whichi's rotatably mounted rearwardly 015180 t ed shaft 13 which is journaledin the bearing 5, said shaft 13 projecting forwardlyfrom the'bearing 5.The shaft 13 is' fixe'd centrally in the day disk 12 through the mediumof an. integral head] Mon the rear end of said shaft, prongs 15 on theperipliery of thehead 1 4: penetrating the day. disk 12 and beingclinched. Printed on the front the face-plate 1 1through,the medium of athread of the, marginal portionof the day disk 12, as at 16, are thedays of the weeks. which are repeated" to provide 31 days'arrangedsubstantially conseplate 1, as jseen'in'Figurel of the cutively readingfrom right to left, said days 16 forming a circular seriesspaced'inwardly from the periphery of the disk 12. 1, .Also, on the disk12, between the days 16 and the peripherynof said disk, are the days ofa single week, as at 17, said days 17 being printedina distinguishingcolor, preferably red. The single week days 17 are also arrangedconsecutively reading from right to left. The daysl'l are positioned,radially with respectto the adjacent days 16. p

" Mounted on the shaft 13 between the, day disk,

12 and the face plate 1"is moon disk'l8 of less diameter than said disk12. The frontof the disk 18 is provided with an elongated, arcuate,concentrio representation 19 of a moon which is preferably colored red.Awash'er 20 is mounted on the shaft 13 between the moon disk 18 and thehead 6 of the bearing 5; If desired, a similar washer may be provided onthe disks 12 and 18.-

the shaft 13 between a v I 11o of theshaft 13 and engaged with the datehand 22. It will thus be seen that by tightening the nut 23 the datehand 22 and the disks 12 and 18 will be frictionally secured togetherand it will further be seen that by loosening said nut 23 the date; hand22 and the disks'12 and 18 may be manually adjusted relative to eachother and tothe fac'e plate 1. In its lower portion, the face plate 1 isprovided with a cut out 24 to facilitateadjustment of the disks 12 and18 when setting -the calendar for each day. Above the bearing 5, thefaceplate 1 is further provided with an opening 25 through which themoon 19 on the disk 18 is observed. 1

opening 26 with which upwardly extending slots 27 communicate. Mountedfor vertical adjustment in the opening 26 is a shutter 28 having awindow 29 therein through which the days .16 or 17 are observed' Thewindow 29v is formed-by.

striking the'material ofythe shutter 28 forwardly .-.-in a manner toprovide an operating. lip or handle 30. The vertical sides of theshutter 28 are formed.

to provide channels 31 for; the=reception of the adjacent portions ottheface plate 1 for S1ldably mounting said shutterin -the opening 26 --;As-wil1 be apparent, when the shutter 28 is in itslower. position, thedays 16 may be observed through the window 29 and whenl said shutter; iselevated to its raised position, the daysl'l may a be observed throughthe window 29.: The slots 27 r -=;accommodate the shutter 28.

operation of the calendar is as follows:f..

12 is then rotated manually until thedesired day 17 appears in thewindow- 29 of theshutter 28. Then,- the disks 12 and 18 are. securedinany suit-- able way against rotation relative to the faceplate 1 whilethe nutl23 isloosened to permit adjust- 1 mentof thedate hand 22 to thenumeral I of thedates '3. The nut-23 is again tightened to frictionally.secure the datehan'd 22 m the disks 12 1 and 18 together.. Of course, th-monthhand 9 is adjusted to indicate the correct month :4. .on the faceplate '1 by .simply'manually rotating said monthhand on the bearing 5'.j

In. order to keep' the disk. .12 ofjproperfsize the annular row or, weekdays 16 is limited to -.=;thirty 'one andthe extra week is placed at thetop ofthefdisk, as. shownin Figure 2.. It ;is

necessary to have more than thirty-one week days on the disk inorder toproperly. set the.

calendar at. thebeginning of a month. For in- ;stance, the month ofJanuary of the year;193 3 besame movement.

gins on a Sunday and ends on a Tuesday. Thus the first'of Februaryoccurs on Wednesday and as February of 1933 only has twenty-eight days,the annular row of week days 16 can be used for these two months.However, if it should happen that the first of any month began on anyother day except Sunday, there would not be' enough days in the row '16to appear correctly in proper sequence, .for' when the -month begins onany other day except Sunday, when the last Tuesday is reached andWednesday is due, the disk would begin to rotate again and Sunday wouldappear.

Thus it is necessary to add six extra days to that does not come onSunday, with a day of 'ithe extra Week 17, it is-simply necessary tomove theshutter when Sunday of the row 17 appears so that Monday of therow 16 will be visible when n v I the calendaris adjusted for the nextday. This 1 Above the dates 3, the face plate l is still-furtherprovided with a substantially rectangular arrangement provides enoughdays on the disk tocoverany month regardless of what day the firstof themonth comeson .andby the use of the representati on 19 of the m'oonbegins to ap pear in the opening 25 of thefac'e plate 1 and the nut 23is again tightened. Before again tightening the nut"'23, it shouldfbeascertained that the correct day 17 still appears in" the window 29 ofthe shutter 28 and thatthe hand 22'still points to'the correfctfdate 3.on the faceplate; 1. Owing to the fact that the months are. o fl.difierent- 7 lengths, the representation 19 offtheimoon'will not always be,absolutely correctlat. all phases of all monthsjbut, it will besubstantially correct.

From its first "quarter, the moon gets a little largereach day untilfullmoon, and then gradually gets a little smaller each dayuntil the lastquarter, and disappears. It can readily be seen that'the shape ofthe'area 19 must'beconcentric in shape to accomplish this result;

The reason it cannot be absolutely correct is, because on some monthsseventeen days elapse between the first and the last quarter, and duringother months only fifteen dayselapse for that When, drawing the area 19,an

I average was struck of the longest and shortest time between.

the first and lastquarter of all months-and was incorporated into thecalendar as a novelty, and notes an accurate instrument of precision."-It may'also-be well to state that the calendar must be changed eachday. As previously stated,
